Sentiment Analysis made easy
Lingmotif 2 is the result of Project FFI2016-78141-P on Sentiment Analysis funded by the Spanish Ministry of Science and Innovation, developed by the Tecnolengua Group at the University of Málaga.
We aim to obtain high-coverage, high-quality lexical resources for Sentiment Analysis with a friendly interface.
Description
Lingmotif is a web application (https://lingmotif.com) that analyzes input texts from a Sentiment Analysis perspective. Basically, it determines the semantic orientation of a text (whether it is positive or negative, and to what extent), by detecting linguistic expressions of polarity, i.e., positivity or negativity.
Unlike most Sentiment Analysis software, Lingmotif is not “just” a classifier, meaning it doesn’t simply classify an input text as positive or negative, it also offers a rich set of quantitative data, a visualization of the “sentiment profile” of the text(s) (including time series), and a detailed qualitative analysis showing text items that were detected as having some kind of semantic orientation. Lingmotif generates HTML files as output, so they can be viewed and searched using any standard browser.
These features make Lingmotif quite unique and make it useful for a wide range of applications.
Currently, Lingmotif is able to analyze English and Spanish texts
